Claims.

This invention relates to powder containers,

and particularly to heads therefor.

, It is an object of the invention to provide a dispensing head which can be made of few and simple parts and at small expense for labor and material, and which will be efficient and reliable in use.

A more specific object of the invention is to provide a dispensing head consisting only of two parts, namely, the head proper, and a closure slide associated therewith, the parts being so constructed and arranged that they may be assembled with one another after both have been fully formed, and the dispensing head proper may then be applied to the top of the powder container with the parts in assembled relation.

It is a feature of the invention that the uniting of the dispensing head proper with the container serves permanently to retain the closure slide against removal.

It is a further feature of the invention that movement of the slide in one direction is limited by a stop formation of the dispensing head member, and movement in the other direction is limited by engagement with the top of the container itself.

Other objects and advantages will hereinafter appear.

In the drawing forming part of this specification, and illustrating a practical and advantageous dispensing container embodying the invention:

Fig. 1 is a plan view of a dispensing container showing the closure slide in closed position;

Fig. 2 is a view similar to Fig. 1 showing the closure slide in open position;

Fig. 3 is a fragmentary view in side elevation of the upper part of the container showing the closure slide in closed position;

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 1 looking in the direction of the arrows, the view being upon a larger scale than Fig. 1;

Fig. 5 is a fragmentary, sectional view taken on the line 5-5 of Fig. 3 looking in the direction of the arrows, the view being upon the same scale as Fig. 4; and

Fig. 6 is a fragmentary, sectional view taken on the line 6--6 of Fig. 2 looking in the direction of the arrows, the view being upon the same scale as Fig. 4.

The container as illustrated comprises a can body I. This desirably consists of a bottom piece (not shown) a side wall member 2 of sheet metal which, as illustrated, is ovate in form,

and a flanged cap or top member 3 which is snugly and permanently fitted to a slightly inset flange 4 at the upper end of the member 2. The top member 3 is formed with a central circular opening 5 in which a dispensing head member 6 is aflixed as will be described a little farther on.

The dispensing head member slidably supports a closure plate 1 which is movable between the closed position illustrated in Figs. 1, 3 and 4, and the open position illustrated in Figs. 2 and 6. The head member 6 is a hollow dome-like member formed of sheet metal. The base portion 8 of this member is circular in cross section and is formed near its lower end with a circumferential boss or rib 9, which is pressed outward by an expanding operation to provide a circumferentially extending shoulder for engaging against the top face of the member 3.

Above the base portion 8 the dispensing member is formed with inwardly sloping side wall portions Ill having arcuate upper edges. The side wall portions it are surmounted by an arcuate boss II in which a dispensing opening 12 is formed. The boss II is formed with inturned side flanges i3 which are integral with the inturned side wall portions Ill. The wall portions IE] and the flange portions [3 form reentrant angles so that the marginal portions of the boss extend outward beyond the bases of the flanges It to form overhanging guide shoulders for guiding and retaining the closure slide l upon the head member. The bOSs H merges at its forward and rear ends with the cylindrical base portion 8 of the head member 6.

The closure plate I consists of an arcuate piece of sheet metal M havinginturned side flanges if for embracing the overhanging shoulders of the boss H. The plate 1 has a central boss iii struck upward from it, the boss [5 serving as an operating finger piece. As seen in Fig. 4.,the under side of the boss |t,which is hollow, does not overlap the dispensing opening I2 when the closure slide is in closed position. The rear end of the slide 1 is formed with a downturned flange ll which coacts with a shoulder l8 formed on the boss 1 I for limiting forward movement of the closure slide 1 relative to the head member 6 to the position illustrated in Fig. 4.

Before the head member 6 has been applied to the top member 3 of the container, the parts 6 and 1 can be assembled and separated at will, there being nothing to limit rearward movement of the closure slide relative to the head member 6. When the members 6 and 1 have been fully formed and have been brought together in assembled relation, the lower end of the base 8 which is disposed below the'circumferential boss 8 is passed through the opening of the member 3. Withthe boss 9 bearing firmly against the upper face of the member 3 the lower extremity of the member 8 is displaced outward to form the outturned flange ii! for retaining the parts strongly and securely against separation. After this operation has been of the closure plate and cooperative with the performed, the member 3 is permanently assembled with the member 2, these members being formed to have a firm driving fit with one another. t

As will be seen from an inspection of Fig. 6;

the closure plate I is free to he slid from the positionrof Fig. 4 to the position of Fig. 6, but not to be removed altogether from the head member 6. The flange l'l strikes the upper face of the member 3 in the Fig. 6 position limiting the movement of the closure slide I. In the position of Fig. 6 the forward edge of the closure slide 7 stands clear of the dispensing opening 12 so that the powder may be dischargedthrough the opening [2. i

It will be observed that the dispensing head consists wholly of two simple sheet metal parts, and that these parts are permanently united with one another, and with the container by a simple swaging or spinning operation, there be i-ng .no need for performing soldering or brazing operations. The fact that the parts are thus united by a simple mechanical operation is a point of som importance because the container parts can be painted or enameled in advance of their assembly with the other parts, without liability of the paint being burned or of the external appearance of the parts being detrimentally affected in any Way.

The curvature of the plate I and the boss H are so related to the height and to the diameter of the'head member 5 that the rear edge of the a plate 1 stands closely adjacent to the junction of the members 3 and 6 when the plate I is in the open position of Figs. 2 and 6.

I have described what I believe to be the best embodiments "of my invention. I do not wish,

however, to be confined to the embodiments shown, but What I desire to cover by Letters Patent is set forth in the appended claims.

I claimzl.

1. A powder container including, in combination, a cap member, a dispensing head member secured thereto, and a closureplate, said head member including an arcuate boss formed with 1 overhanging guide shoulders and with a-stcp shoulder and having a dispensing opening, and
